Answer:
Robyn model makes more sense and Mark's is nonsense
Step-by-step explanation:
In this question ,calculations not required .All we have to do is consider each model logically .
Marks
Marks model shows 20 rather than 2 which means 200 is 10 times as much as 20. It does not make any sense.
Robyn
Robyn model shows 2 which means 200 is 100 times as much as 2 and this is not only correct but also makes sense because 100 *2=200
Answer:
The pecans used in the mixture = 8 kg
The almonds used in the mixture = 17 kg
Step-by-step explanation:
The cost of per kg of pecans = $28.50
The cost of per kg of almonds = $22.25
Now, total weight of mixture = 25 kg
Let us assume the weight of pecans in the mixture = m kg
So, the amount of almonds in the mixture = Total weight - Weight of Pecans
= (25 - m) kg
Now, cost of m kg pecans = m x ( cost of 1 kg pecans) = m x ( $ 28.50)
= 28.50 m
cost of (25- m) kg almonds = (25 -m) x ( cost of 1 kg almonds)
= (25 - m) x ( $ 22.25)
= 556.25 - 22.25 m
Total cost of 25 kg of mixture = 25 x ( $24.25) = $606.25
Now, Total Cost of (almonds + Pecans) = Total cost of mixture
⇒28.50 m + 556.25 - 22.25 m = $606.25
or,6.25 m = 50
or, m = 50/6.25 = 8
Hence, the pecans used in the mixture = m = 8 kg
And the almonds used in the mixture = (25 - m) = 25 - 8 = 17 kg
<span>D. Let x represent the number of trays of dog bone treats made and y represent number of trays of oatmeal dog treats made.</span>
Answer:
$122.89
Step-by-step explanation:
The two number you have in this equation are 108.75 and 13% (or .13)
first you want to multiply 108.75 to .13
108.75 * .13 = 14.1375
Now, you add 14.1375 to 180.75 and round to the nearest hundredth
180.75+ 14.1375=122.8875
$122.89
Answer:
<u></u>
Explanation:
The figure attached shows the <em>Venn diagram </em>for the given sets.
<em />
<em><u>a) What is the probability that the number chosen is a multiple of 3 given that it is a factor of 24?</u></em>
<em />
From the whole numbers 1 to 15, the multiples of 3 that are factors of 24 are in the intersection of the two sets: 3, 6, and 12.
There are a total of 7 multiples of 24, from 1 to 15.
Then, there are 3 multiples of 3 out of 7 factors of 24, and the probability that the number chosen is a multiple of 3 given that is a factor of 24 is:
<em><u /></em>
<em><u>b) What is the probability that the number chosen is a factor of 24 given that it is a multiple of 3?</u></em>
The factors of 24 that are multiples of 3 are, again, 3, 6, and 12. Thus, 3 numbers.
The multiples of 3 are 3, 6, 9, 12, and 15: 5 numbers.
Then, the probability that the number chosen is a factor of 24 given that is a multiple of 3 is:
